clk: Add non CONFIG_HAVE_CLK routines

Many drivers are shared between architectures that may or may not have HAVE_CLK selected for them. To remove compilation errors for them we enclose clk_*() calls in these drivers within #ifdef CONFIG_HAVE_CLK, #endif.

This patchset removes the need of these CONFIG_HAVE_CLK statements, by introducing dummy routines when HAVE_CLK is not selected by platforms. So, definition of these routines will always be available. These calls will return error for platforms that don't select HAVE_CLK.
